Stuck at the "Part 5, Level 1: Sculpting", where Andrew works on the fixing the Icing droplets
I don't know what process you used, but here's the proper way to do it:
Press 'o' on your keyboard to enable proportional editing in edit mode (first remember to undo your process of making the icing stick to the donut) and then grab one vertex on the icing which you want to stick to the donut. then press 'G' to move. You will see a circle surrounding that vertex. Use the scroll wheel on your mouse to change the size of the circle. Then, make the circle big enough to cover the part of the icing you want to stick to the donut. Then just move (remember to press 'G' or you won't see a circle or you won't be able to move your icing.) the vertex. You will see that some more verticies re moving with that single vertex. Change the size of the circle by using the scroll wheel on your mouse to specifiy how many verticies you want to move. That is how you can stick the icing to the donut.
